MECHANISM OF TYPE-WRlTERS- Patented a 29,1907.

to the Spacing Mechanism of Type-\Vriters, l

of which the following is the specification. l

This invention relatesto the spacing .mech- 'anism of type-writers, andmore especially type-writers'havmg front-striking gear and -tl1e formerbeing operated from the universal bar for the fork of the printtheribbon longia device operated raising and depressing ing-ribbon and formoving tudinally.

The object in machines of of the invention is to arrange the kind abovereferred to controlling or spacing del vice can be operated withoutnecessitating i the operation of the device which moves the inkin'g-ribbon.

. It is already known to have been so provided that when the spacing-keyis operated but in such known xfmount'ed on one. or two levers .leve'rdv is secured to the shaft 0 and adapted to cause in the bar, suchdevice the ribbon, with its guide, is out of action; arrangements theribbon and its guide are not moved from the univer; sal bar driving thecontrolling or. spacing device for the paper-carr age.

According. to the present .'Iivention, al-

though the device for imparting a transverse and ongitudinal movementtothe ribbon' is are mounted on levers n,

I he letterrkeys one of which is shown, %ivotally' mounted in 1 the;usual, manner.

ach lies upon the universal bar i,a'ndwhenletter key is struck thecorresponding the universal bare, which ever a lever n depresses thenoperates both the pa trolling device and the rib on mechanism, through arod it (having a slotted end g, which engages the pinf on thedetent-pawl carrier or lever) an the latter 'throu h a bell-crank lever7c and levers Z, mounte on the shaft m. The slotted end g of the rod henables the spacingpawl E to be operated bythe space-key withoutaffecting the lever k, and therefore the ribbon mechanism. In themodification illustrated the space-key lever I) really .acts upon theuniversal bar i; but the stroke Thesev levers are er-carriage-eoneimparted to the bar by that lever is so slight as to be insufficient tooperate the ribbon v mechanism.

Having now particularly described and ascertained the nature ofmy saidinvention and in what manner the same is to be per- ,i formed, I declarethat what I claim 1s V The combination n a type-Writer, ofcarrlage-controllmg mechanism, ribbon mechanlsm, key-levers, a leveroperated by sa d in operative connection with the universal levers, arod connected to said lever havinga is not brought-into action when thespace-key is struck, as this latter is in the form of or operates abell-crank lever the carriage coni device, but does not imbar to eilectthe operation of .the ribbon mechanism.

Referring to the accompanying drawings, Figure 1 is a side sectionalelevation of art of' a typewriter .with spacing and rib on car arrangedaccording. to the invention.

" $22, is a plan corresponding thereto.

in carrying out the invention according to one modification the spacekey or bar a is l b l), secured to a shaft 0, pivoted mthemachine-frame. to engage the detent-pawl carrier or dog thepaper-carriage-controlling device, so as usual manner an advance of thecarriage equal to the width of a letter whenever the space-key a isstruck.

slot in its upper end, a pin on the carriagecontrolling mechanismengaging in said slot, a connection from said lever to the ribbonmechanismpso thato'n the depression of a key both the carriage andribbon mechanisms space-key and connections therefrom to thecarriage-controlling mechanism for operating the saidcarriagecontrolling mechanism, the pin in the'carriage-co'ntrollingmechanism working in the slot during this operation whereby thecarriage-controlling mechanism is operated independently*of"theribbon'mechanism, substantially as described.

' In'witness whereof I have hereunto set'my hand in presence of twowitnesses.
